this question is analyzed and performed in full, a reason is given for each successive step in the operation, and a rule applicable to the solution of all similar questions is thence deduced.

An arithmetic for common schools should contain concise and accurate definitions of all arithmetical terms, lucid illustrations of the principles and properties of whole and fractional numbers, and rules deduced from those illustrations; also a sufficient number of such practical questions, as will often occur in the transaction of business.

This work contains the principles of Life and Health Insurance, comprising tables on which the calculations of premiums are based, prepared by the President of the New England Mutual Life Insurance Company, and the Secretary of the Massachusetts Health Insurance Company, of Boston. It also contains Geometrical Definitions illustrated by diagrams, Mensuration of Surfaces and Solids, Strength of Materials, Mechanical Powers, Specific Gravity of Bodies, a Table of all the Gold and Silver Coins in circulation, showing their real value in dollars and cents; Forms of Bills of Exchange, Drafts, Promissory Notes, Orders, and Receipts.

The article on Specific Gravities has been copied from. Ingram's Mathematics, and the articles on the Mechanical Powers and Strength of Materials have been selected partly from the Library of Useful Knowledge and the Mechanic's Calculator.

The author, having had forty years' experience in teaching, has endeavored to prepare an Arithmetic which shall lighten the labors of the teacher and facilitate the progress of the pupil. With what success the work has been executed, remains for teachers and pupils to decide.

To the teachers of youth in the United States, the American Arithmetic is respectfully dedicated, with the sincere desire that their labors in the cause of education may be duly appreciated and rewarded.

BOSTON, OCTOBER 1, 1847.

JAMES ROBINSON.
